As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0033] The Channel State Information (CSI) architecture can be divided into downlink CSI and uplink CSI. The downlink CSI architecture includes downlink physical channels and downlink reference signals; the uplink CSI architecture includes uplink physical channels and uplink reference signals.

[0034] The downlink physical channel is usually used to transmit data, and the downlink reference signal is usually used to perform channel estimation to obtain downlink channel state information (CSI). The uplink physical channel is usually used to transmit uplink data, and the uplink reference signal is usually used to perform channel estimation to obtain uplink channel state information (CSI).

[0035] Typically, the terminal may determine through higher layer signaling or default rules that the CSI report may include one of: 'none', 'cri-ri-pmi-cqi', 'cri-RI-i1', 'cri-RI-CQI', 'cri-RSRP', 'cri-SINR', 'ssb-Index-RSRP', 'ssb-Index-SINR' or 'cri-RI-LI-PMI-CQI'.

[0036] If the terminal is configured with a CSI report configuration (CSI-ReportConfig) and the upper layer parameter report quantity (reportQuantity) is set to "none", the terminal will not report anything for the CSI-ReportConfig.

[0037] If the reportQuantity field in the high-level parameter CSI-ReportConfig is set to 'cri-RI-CQI', the terminal assumes that the precoding matrix indicator (PMI) is a unit matrix and only needs to report one or more of the CSI reference signal (CSI-RS) resource indicator (CSI-RS Resource Indicator, CRI), rank indicator (RI) and channel quality indicator (CQI), without reporting PMI.

[0038] For the Type 2 (Type 2) series CSI reports carried on the Physical Uplink Shared Channel (PUSCH), they are usually divided into two parts, CSI report part 1 (Part 1) and CSI report part 2 (Part 2). Each part is independently encoded, and the size of CSI report part 2 can be determined by CSI report part 1.

[0039] Currently, the protocol supports carrying one CSI report on an uplink channel resource (e.g., Physical Uplink Control Channel (PUCCH) or PUSCH) and feeding it back to the network side device, or carrying multiple CSI reports on an uplink channel resource (PUCCH or PUSCH) and feeding it back to the network.

[0040] If the payload size of the CSI report is too large to be carried, the terminal may discard part of the CSI report or the entire CSI report according to the protocol.

[0041] For a PUCCH associated with a CSI report, the PUCCH resource selects one PUCCH resource from multiple PUCCH resources preconfigured by a network-side device to carry the CSI report according to an uplink active bandwidth part (Bandwidth Part, BWP) identifier (ID).

[0042] For the case of a PUSCH associated with a CSI report, multiple time slot offsets are indicated in the high-level signaling CSI report setting. The network-side device indicates one of the time slot offsets through downlink control information (DCI) for the terminal to determine the time domain position of the PUSCH, and further determines the frequency domain position and other parameters of the PUSCH through DCI indication.

[0043] In the case where multiple CSI reports are carried on one PUCCH, usually after multiple PUCCH resources carrying CSI reports collide, the multiple CSI reports are mapped to a pre-configured PUCCH resource. When the pre-configured PUCCH resource cannot carry multiple CSI reports, the terminal's behavior may be to discard part of the content of some CSI reports or discard some CSI reports according to the protocol.

[0044] For the case where multiple CSI reports are carried on one PUSCH, the network usually triggers multiple non-periodic CSI reports or CSI reporting through DCI. For each CSI report setting, multiple time slot offsets are indicated. The network-side device indicates one of the time slot offsets through DCI. The terminal determines the position of the PUSCH based on the maximum value of multiple time slot offsets associated with multiple CSI reports, and further determines the frequency domain position and other parameters of the PUSCH through DCI indication. When the pre-configured PUSCH resources cannot carry multiple CSI reports, the terminal's behavior may be to discard part of the content of some CSI reports or discard some CSI reports according to the protocol.

[0045] If the payload size of a CSI report is variable, for example, an MTRP CSI report, the terminal can select a TRP. In extreme cases, the terminal selects one TRP to obtain the CSI report or the terminal selects all TRPs to obtain the CSI report. In this case, the payload size of the CSI report varies greatly.

[0046] To avoid loss of CSI report content, network-side devices may need to configure uplink channel resources based on the maximum case scenario. If the payload size of future CSI reports is large and has a wide range of variations, this may result in significant resource waste. Furthermore, the network-side device's search for a large, continuous uplink channel resource may affect network resource allocation flexibility.

[0047] It can be seen that in the related art, the terminal carries the obtained CSI report or multiple CSI reports onto an uplink channel resource and feeds them back to the network side device according to high-level signaling or protocol agreement. If the uplink channel resource is not large enough, the payload size of the CSI report may be too large, resulting in an inability to carry it. If the network side device configures the uplink channel resources based on the maximum load size of the CSI report in order not to lose the CSI report content, on the one hand, it may cause a large waste of resources. On the other hand, the network side device needs to find a larger continuous uplink channel resource, which may affect the flexibility of resource allocation. In response to the above problems, an embodiment of the present application provides a feedback solution for channel state information reporting to solve at least one of the above problems.

[0048] The following describes in detail the channel state information reporting feedback scheme provided by the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0049] Figure 2 A flow chart showing a method for feedback of channel state information report in an embodiment of the present application is shown. The method 200 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. Figure 2 As shown, the method may include the following steps.

[0050] S210: The terminal determines multiple uplink channel resources associated with at least one target CSI report.

[0051] In the embodiment of the present application, the at least one target CSI report may be a CSI report to be fed back by the terminal. In the case where there is one target CSI report, one target CSI report is associated with multiple uplink channel resources. Optionally, the terminal determines that at least one uplink channel resource that ultimately carries the target CSI report is at least part of the multiple uplink channel resources determined by the terminal. This can be understood as the terminal determining multiple uplink channel resources associated with a target CSI report based on target network signaling (for example, radio resource control (RRC), media access control layer control element (MAC-CE), downlink control information (DCI), etc.). The terminal further determines at least one uplink channel resource from multiple uplink channel resources according to the method indicated by the network or the method agreed upon by the protocol or by its own choice. The terminal carries the target CSI report on the at least one uplink channel resource and transmits it to the network side device. Further, the network side device determines at least one uplink channel resource that carries the CSI report among the multiple uplink channel resources determined by the terminal in the same manner as the terminal, and receives or demodulates the target CSI report on the at least one uplink channel resource.

[0052] In S210, the terminal can determine multiple uplink channel resources associated with a target CSI report based on the received target network signaling. For example, the terminal receives multiple DCI triggers for the same CSI report (for example, the CSI report ID is the same) at the same time, and the multiple uplink channel resources associated with the multiple DCIs are the multiple uplink channel resources associated with the CSI report. For another example, the network side device can configure a CSI report to be associated with multiple uplink channel resources through high-layer signaling. For another example, the network side device can trigger or activate the one CSI report through signaling, and the CSI report can be carried on the multiple uplink channel resources associated with the CSI report by the network high-layer signaling.

[0053] Optionally, one CSI report may be associated with multiple uplink channel resources in the following situations:

[0054] 1) When a terminal receives multiple DCIs triggering the same CSI report in the same time period (e.g., the same symbol, the same group of symbols, the same time slot, the same group of time slots), the CSI report can be understood as one CSI report being associated with multiple uplink channel resources;

[0055] 2) The network-side device configures a CSI report to be associated with multiple uplink channel resources through high-layer signaling. For the CSI report, it can be understood that one CSI report is associated with multiple uplink channel resources;

[0056] 3) The terminal receives a DCI that triggers a CSI report and multiple uplink channel resources. The CSI report can be understood as one CSI report being associated with multiple uplink channel resources.

[0057] In an embodiment of the present application, when there are multiple target CSI reports, at least one of the multiple target CSI reports is associated with multiple uplink channel resources, or at least one of the multiple uplink channel resources is associated with multiple target CSI reports, that is, the target CSI reports and uplink channel resources do not have a one-to-one correspondence. The terminal may determine or select at least one uplink channel resource from the multiple uplink channel resources configured or indicated by the network-side device to carry the multiple target CSI reports. Optionally, the multiple target CSI reports are carried on the at least one uplink channel resource and fed back to the network-side device, wherein at least one uplink channel resource may be associated with multiple target CSI reports, that is, not necessarily one CSI report corresponds to one uplink channel resource. Alternatively, the terminal may, based on the multiple uplink channel resources configured or indicated by the network-side device, carry the multiple target CSI reports on multiple uplink channel resources and feed them back to the network, wherein at least one uplink channel resource is associated with multiple target CSI reports, that is, not necessarily one CSI report corresponds to one uplink channel resource.

[0058] In an embodiment of the present application, the terminal may determine multiple uplink channel resources associated with multiple target CSI reports based on network signaling. For example, if the terminal receives a DCI triggering multiple uplink channel resources and multiple CSI reports, the terminal may determine that the multiple CSI reports are associated with the multiple uplink channel resources.

[0059] Optionally, multiple CSI reports may be associated with multiple uplink channel resources, which may include the following situations:

[0060] 1) The terminal receives a DCI triggering multiple CSI reports and multiple uplink channel resources. In this case, it can be understood that multiple CSI reports are associated with multiple uplink channel resources;

[0061] 2) The network-side device triggers multiple CSI reports through a Medium Access Control-Control Element (MAC-CE) signaling. Each of the multiple CSI reports is associated with an uplink channel resource. In this case, multiple CSI reports can be understood as being associated with multiple uplink channel resources.

[0062] 3) The terminal receives multiple DCIs that trigger multiple CSI reports and multiple uplink channel resources. The terminal further determines the association mode of the multiple CSI reports and the multiple uplink channel resources based on the indication of the network signaling, wherein one association mode is that the multiple CSI reports in the embodiment of the present application are associated with multiple uplink channel resources, that is, not one CSI report corresponds to one uplink channel resource.

[0063] Optionally, the multiple uplink channel resources mentioned above may be multiple channel resources of the same type, where the same type may be understood as at least one of the same function, the same protocol definition, the same property, and the same content. For example, the multiple uplink channel resources may all be uplink control channel resources (PUCCH), or the multiple uplink channel resources may all be uplink shared channels (PUSCH).

[0064] Optionally, at least one of the multiple uplink channel resources may be of a different type from the other uplink channel resources. For example, at least one target CSI report is associated with two uplink channel resources, one of which is a PUSCH and the other is a PUCCH.

[0065] In the embodiment of the present application, the multiple uplink channel resources may be uplink channel resources associated with multiple carriers or multiple BWPs, or may be uplink channel resources associated with the same carrier or the same BWP.

[0066] In the embodiment of the present application, the multiple uplink channel resources may be uplink channel resources associated with at least one of the following: multiple TRPs, multiple Transmission Configuration Indicators (TCIs), multiple spatial relations, multiple physical cell IDs, and multiple serving cells. They may also be uplink channel resources associated with the same at least one of the following: TRPs, TCIs, spatial relations, physical cell IDs, and serving cells.

[0067] S212: The terminal feeds back the at least one target CSI report based on the determined multiple uplink channel resources.

[0068] The technical solution provided by the embodiments of the present application can provide a CSI report or multiple CSI reports to the network in a timely, effective and complete manner. For example, in the following situations, the CSI report can be provided to the network side device in a timely and effective manner:

[0069] 1) The size of a CSI report is large, and a single uplink channel resource may not be able to fully feed back the CSI report. Multiple uplink channel resources are required to carry the CSI report and then feed it back to the network-side device;

[0070] 2) When the channel quality of a pre-allocated uplink channel resource is poor, multiple uplink channel resources can be pre-allocated to ensure reliability. The network-side device uses signaling to indicate that one of the uplink channel resources carries the CSI report, and then feeds back to the network-side device.

[0071] 3) A CSI report includes multiple CSI sub-reports associated with multiple TRPs. A single uplink channel resource may not allow each CSI sub-report to reach the associated TRP in a timely and reliable manner. In this case, multiple CSI sub-reports can be allocated to multiple uplink channel resources and directly fed back to each TRP via multiple uplinks.

[0072] 4) An uplink channel resource is limited. Multiple CSI reports cannot be carried on one uplink channel resource. Multiple uplink channel resources can be triggered to carry multiple CSI reports.

[0073] In addition, by adopting the technical solution provided in the embodiment of the present application, the network side device can flexibly allocate multiple uplink channel resources for feedback of CSI reports. The terminal feeds back the target CSI report based on the target CSI report to be fed back and the multiple uplink channel resources associated with the target CSI report, thereby eliminating the need for the network side device to allocate a large continuous uplink channel resource, avoiding resource waste, and improving the flexibility of resource allocation.

[0074] In an optional implementation of an embodiment of the present application, when the number of target CSI reports is 1, the terminal may map the CSI report to at least one uplink channel resource and feed it back to the network side device based on the size of the CSI report. Therefore, in this optional implementation, the terminal feeding back the target CSI report based on the determined multiple uplink channel resources may include: the terminal mapping the target CSI report to at least one uplink channel resource and feeding it back to the network side device based on the size of the target CSI report. In this optional implementation, when one uplink channel resource cannot carry the target CSI report, the terminal may split the target CSI report into multiple CSI sub-reports or multiple CSI report parts (for example, CSI report part 1 and CSI report part 2), and carry or map them to multiple uplink channel resources respectively and feed them back to the network side device. Among them, splitting the target CSI report into multiple CSI sub-reports or multiple CSI report parts can be understood as dividing all contents associated with the target CSI report (for example, at least one of CRI, RI, PMI, CQI, LI, spatial domain information of the channel, time domain information of the channel, delay domain information of the channel, angle information of the channel, multipath information of the channel, and correlation information of the channel) into multiple parts, each of which can be called a CSI sub-report or a CSI report part.

[0075] Optionally, mapping the CSI report to at least one uplink channel resource and feeding it back to the network-side device may include at least one of the following steps:

[0076] Step 1: The terminal determines that the target CSI report cannot be carried on an uplink channel resource;

[0077] Step 2: The terminal determines that the target CSI report can be carried on multiple uplink channel resources;

[0078] Step 3: The terminal determines the uplink channel resources on which the target CSI report needs to be carried;

[0079] Step 4: The terminal splits the target CSI report into multiple CSI sub-reports or multiple CSI report parts;

[0080] Step 5: The terminal carries or maps multiple CSI sub-reports or multiple CSI report parts onto the uplink channel resources that need to be carried and feeds them back to the network;

[0081] In the embodiment of the present application, the execution order of the above steps 1 to 5 is not strictly limited. In specific applications, the execution order of steps 1 to 5 can be determined according to actual settings.

[0082] For the above step 1, the terminal can determine the target CSI report based on the high-level signaling related to the target CSI report configuration indicated by the network-side device, and obtain the payload size of the target CSI report. Further, the terminal determines a carried uplink channel resource. Optionally, if the target CSI report is associated with multiple uplink channel resources, the uplink channel resource determined by the terminal can usually be the first uplink channel resource indicated by the network-side device among the multiple uplink channel resources associated with the target CSI report, or the earliest uplink channel resource among the multiple uplink channel resources, or an uplink channel resource of a specific format among the multiple uplink channel resources, or an uplink channel resource indicated by network signaling. Further, the terminal determines whether the payload size that can be carried by the one carried uplink channel resource can carry the target CSI report.

[0083] Optionally, if it is bearable, the CSI report is carried on an uplink channel resource of a determined bearer and fed back to the network side device.

[0084] Optionally, if the target CSI report cannot be carried, the terminal determines whether the target CSI report can be carried in multiple uplink channel resources (step 2). The determination method may be one of the following:

[0085] 1. The terminal determines, based on network signaling, that the target CSI report can be carried on multiple uplink channel resources. For example, the terminal receives a network signaling indication and determines that the target CSI report can be carried on multiple uplink channel resources;

[0086] 2. The terminal determines, according to the protocol, that the target CSI report can be carried on multiple uplink channel resources. For example, if the terminal determines that the target CSI report is associated with multiple uplink channel resources, the target CSI report can be carried on multiple uplink channel resources.

[0087] Optionally, if the terminal determines that the target CSI report cannot be carried in multiple uplink channel resources, the terminal does not feed back the target CSI report according to the method agreed upon in the protocol or carries part of the content of the target CSI report on a determined uplink channel resource and feeds it back to the network.

[0088] Optionally, if the terminal determines that the target CSI report can be carried on multiple uplink channel resources, the terminal optionally determines the multiple uplink channel resources on which the target CSI report needs to be carried (step 3). This can be understood as the terminal determining, from the multiple uplink channel resources associated with the target CSI report, at least some uplink channel resources for carrying the target CSI report. Optionally, the number of uplink channel resources determined by the terminal is agreed upon in the protocol, fed back by the terminal, or indicated by network signaling.

[0089] Optionally, when determining the multiple uplink channel resources that carry the target CSI report, the terminal can determine the priority of each uplink channel resource according to the time domain position or frequency domain position of the multiple uplink channel resources associated with the target CSI report, and then select the first few uplink channel resources with the highest priority. Therefore, in this optional implementation method, the terminal maps the target CSI report to at least one of the uplink channel resources according to the size of the target CSI report and feeds it back to the network side device, including: the terminal prioritizes the multiple uplink channel resources according to the time domain position or frequency domain position of each of the uplink channel resources, determines at least one of the uplink channel resources that matches the size of the target CSI report in descending order of priority, and maps the target CSI report to at least one of the uplink channel resources in turn and feeds it back to the network side device. Through this optional implementation method, it can be ensured that the target CSI report is mapped to an uplink channel resource with a higher priority.

[0090] In the above optional implementation, the terminal may determine the order or mapping order of the multiple uplink channel resources associated with the target CSI report according to the protocol agreement or network signaling instructions. For example, the order of the multiple uplink channel resources is determined according to their associated time domain positions and frequency domain positions. Optionally, one way is to determine the order of the multiple uplink channel resources in the order of frequency domain first and time domain second, such as Figure 3 As shown, a square represents an uplink channel resource, the vertical direction represents the frequency domain position relationship, and the horizontal direction represents the time domain position relationship. The smaller the number in the square, the higher the priority. Optionally, another way is to determine the order of multiple uplink channel resources in the order of time domain first and frequency domain second, such as Figure 4 As shown, the smaller the number in the box, the higher the priority.

[0091] For another example, multiple uplink channel resources are configured by network signaling. The terminal can determine the priority order of the multiple uplink channel resources based on the configuration order of the multiple uplink channel resources in the network signaling, that is, the uplink channel resources configured first have the highest priority, and the uplink channel resources configured last have the lowest priority.

[0092] After determining the priority order of multiple uplink channel resources associated with the target CSI report, the terminal determines the uplink channel resources mapped to the target CSI report in sequence according to the priority order until the selected multiple uplink channel resources can carry the payload of the target CSI report, or until the preset number of uplink channel resources is met.

[0093] For the above optional implementation, the terminal determines the uplink channel resources in order of priority until the selected multiple uplink channel resources can carry the payload of the CSI report. Optionally, at least one of the format, position, and carryable payload of the uplink channel resources determined by the terminal in order of priority needs to meet the protocol agreement or terminal capability or network signaling indication until the determined multiple uplink channel resources can carry the payload of the CSI report. It can be understood that the terminal determines the uplink channel resources not only needs to consider the priority order of the uplink channel resources, but also needs to consider the format or position or carryable payload of the uplink channel resources.

[0094] Optionally, the terminal determines that both uplink channel resources associated with the target CSI report are used to carry the CSI report. This means that when the CSI report is associated with two uplink channel resources, the terminal determines that the target CSI report needs to be carried on the two uplink channel resources and feeds this back to the network-side device. This method is typically used when the CSI report is associated with two uplink channel resources. In this case, the terminal directly determines that both uplink channel resources are used to carry the CSI report.

[0095] Optionally, before the terminal determines the multiple uplink channel resources that the target CSI report needs to be carried on (step 3) or after the terminal determines whether the target CSI report can be carried on multiple uplink channel resources (step 2), the terminal can split the target CSI report into multiple CSI sub-reports according to network signaling or protocol agreement (step 4). For example, when the target CSI report includes 2 parts (for example, part 1 and part 2), the terminal splits the target CSI report into 2 CSI sub-reports, the first CSI sub-report is part 1, and the second CSI sub-report is part 2. Further, the terminal determines that the two uplink channel resources carry the first CSI sub-report and the second CSI sub-report, respectively. Optionally, the specific determination process can refer to the above description of step 3. For another example, the terminal splits the target CSI report into two CSI sub-reports according to the protocol agreement, wherein the first CSI sub-report is associated with at least one of the channel quality indicator (CQI), rank indicator (RI), CSI-RS resource indicator (CRI), layer indicator (LI), and non-zero coefficient number indication, and the second CSI sub-report is associated with the precoding matrix indicator (PMI). Then, the terminal determines that two uplink channel resources carry the first CSI sub-report and the second CSI sub-report, respectively. Optionally, the specific determination process can refer to the above description of step 3.

[0096] Optionally, another method is that when the terminal determines the multiple uplink channel resources that the target CSI report needs to carry (step 3), the terminal splits the CSI report into multiple CSI sub-reports (step 4), for example: the terminal determines the first uplink channel resource for carrying the CSI report and the payload size that can be carried, divides a part of the content from the CSI report to form the first CSI sub-report, and then carries it in the first uplink channel resource. Further, the terminal determines the second uplink channel resource for carrying the CSI report and the payload size that can be carried, divides a part of the content from the remaining CSI report to form the second CSI sub-report, and then carries it in the second uplink channel resource, until all the content of the CSI report is carried in the multiple uplink channel resources. Optionally, when the terminal divides the CSI report, it divides it according to the mapping order of the CSI report content agreed upon in the protocol.

[0097] Optionally, another method is that after the terminal determines the multiple uplink channel resources that need to be carried by the target CSI report (step 3), the terminal splits the target CSI report into multiple CSI sub-reports (step 4), that is, the terminal first determines a certain number of uplink channel resources according to network instructions or protocol agreements, and then divides the target CSI report into multiple CSI sub-reports and maps them to a certain number of uplink channel resources for feedback. For example, taking two uplink channel resources as an example, the terminal determines the first uplink channel resource used to carry the target CSI report and the payload size that can be carried, divides a portion of the content from the target CSI report to form the first CSI sub-report, and then carries it in the first uplink channel resource. Further, the terminal determines the second uplink channel resource used to carry the target CSI report and the payload size that can be carried, divides a portion of the content from the remaining target CSI report to form the second CSI sub-report. If part of the content in the target CSI report still exists, the terminal does not feedback the corresponding remaining content. Optionally, when dividing the target CSI report, the terminal divides it according to the mapping order of the target CSI report content agreed upon in the protocol.

[0098] For another example, when the target CSI report includes two parts (part 1 and part 2), the terminal splits the target CSI report into two CSI sub-reports, with the first CSI sub-report being part 1 and the second CSI sub-report being part 2. Furthermore, the terminal determines two uplink channel resources to carry the first CSI sub-report and the second CSI sub-report, respectively. If an uplink channel resource cannot carry the CSI sub-report, the terminal discards part of the CSI sub-report in the order or manner agreed upon in the protocol.

[0099] Through the above implementation, the content of the target CSI report can be fed back to the network to the maximum extent possible, avoiding the issue of discarding the entire or partial target CSI report when an uplink channel resource cannot carry the target CSI report. Alternatively, this approach can also increase the flexibility of network configuration of uplink channel resources, avoiding resource waste caused by allocating excessively large uplink channel resources when the network cannot determine the target CSI report size.

[0100] In addition, optionally, when the target CSI report is divided into multiple CSI sub-reports carried on multiple uplink channel resources, the first target CSI sub-report carried by the first uplink channel resource may include at least one indication information, so that after the network decodes the first uplink channel resource, it can determine the payload size of the CSI sub-reports carried by other uplink channel resources or determine the number of uplink channel resources.

[0101] In an optional implementation, when a target CSI report is associated with multiple uplink channel resources, the terminal determines the resource union of the at least one uplink channel resource, maps the target CSI report to the resource union and feeds it back to the network side device. Therefore, in this optional implementation, the terminal feeding back the at least one target CSI report based on the determined multiple uplink channel resources may include: the terminal determines the resource union of the multiple uplink channel resources, maps the target CSI report to the resource union and feeds it back to the network side device. In this implementation, the terminal determines a resource union based on the multiple uplink channel resources associated with the target CSI report, the resource union including frequency domain resources or time domain resources. After determining the resource union, the terminal maps the target CSI report to the resource union and feeds it back to the network side device.

[0102] In the embodiments of the present application, the resource set can be understood as the resource set of at least one of the time domain, frequency domain, and spatial domain resources of multiple uplink channel resources. If the multiple uplink channel resources do not overlap, the resource set can be understood as the sum of at least one of the time domain resources, frequency domain resources, and spatial domain resources occupied by the multiple uplink channel resources. Typically, the terminal uses the same transmission parameters for transmission of the multiple uplink channel resources, such as the modulation order and code rate.

[0103] Optionally, when the terminal determines the resource union, the resource union satisfies at least one of the following:

[0104] 1) The number of available resource elements (REs) associated with each orthogonal frequency division multiplex (OFDM) symbol is the same; for example, the number of REs associated with each OFDM symbol in all OFDM symbols associated with the resource set is the same.

[0105] 2) The frequency domain interval between the frequency domain resources associated with any two OFDM symbols does not exceed a first predetermined value; for example, among all OFDM symbols associated with the resource set, the frequency domain interval between the frequency domain resources associated with any two OFDM symbols does not exceed a first predetermined value, wherein the first predetermined value can be at least one of a specific number of REs, a number of resource blocks (RBs), and a number of resource block groups (RBGs). Optionally, the specific number of REs, the number of RBs, or the number of RBGs is a value of UE capability feedback.

[0106] 3) The time domain interval between any two adjacent OFDM symbols does not exceed a second predetermined value. For example, among all OFDM symbols associated with the resource union set, the time domain interval between any two adjacent OFDM symbols does not exceed a second predetermined value. The second predetermined value may be a specific number of OFDM symbols or a specific number of time slots. Optionally, the specific number of symbols or time slots is a value fed back by a UE capability.

[0107] Optionally, the terminal mapping the target CSI report to the resource set and feeding it back to the network-side device may include the following steps:

[0108] Step 1: The terminal determines uplink transmission parameters;

[0109] In step 2, the terminal maps the target CSI report to the resource set based on the uplink transmission parameter and feeds the result back to the network side device.

[0110] The uplink transmission parameters may be understood as parameters required to map the target CSI report to the resource set, such as modulation order, code rate, etc. Optionally, the uplink transmission parameters may include at least one of the following:

[0111] i. Bit rate;

[0112] ii. Maximum bit rate;

[0113] iii. Modulation order;

[0114] iv. Resource scaling factor; The resource scaling factor is used to limit the number of resource elements allocated to uplink control information (UCI) on the PUSCH.

[0115] v.Subcarrier spacing;

[0116] vi. CSI offset value; the CSI offset value is used to adjust the ratio of the number of UCI bits to the number of PUSCH or uplink shared channel (UL-SCH) bits)

[0117] Optionally, the terminal determining the uplink transmission parameter may include at least one of the following:

[0118] a) the terminal determines a maximum value among multiple transmission parameters associated with multiple uplink channel resources as the uplink transmission parameter;

[0119] b) the terminal determines a minimum value among multiple transmission parameters associated with multiple uplink channel resources as the uplink transmission parameter;

[0120] c) The terminal determines the transmission parameter associated with the first uplink channel resource among the multiple uplink channel resources as the uplink transmission parameter; for example, the transmission parameter associated with the first configured uplink channel resource among the multiple uplink channel resources.

[0121] d) The terminal determines the uplink transmission parameter based on the third network signaling; for example, the network side device may indicate the uplink transmission parameter through the third network signaling.

[0122] e) The terminal determines the uplink transmission parameter based on a rule agreed upon in a protocol, wherein the rule agreed upon in the protocol is related to a transmission parameter associated with at least one uplink channel resource among the multiple uplink channel resources; for example, the rule agreed upon in the protocol indicates that the uplink transmission parameter is the transmission parameter associated with the earliest uplink channel resource among the multiple uplink channel resources. For another example, the protocol agrees on a calculation method, whereby the uplink transmission parameter is obtained by calculating the transmission parameters of multiple uplink channel resources.

[0123] f) The terminal determines the uplink transmission parameters based on the default transmission parameters agreed upon in the protocol. For example, the protocol may agree upon a set of default transmission parameters, and the terminal determines the uplink transmission parameters as the default transmission parameters.

[0124] The technical solution provided by the above implementation can be understood as follows: each uplink channel resource among multiple uplink channel resources is associated with one or one group of uplink transmission parameters, and the uplink transmission parameters associated with different uplink channel resources may be different. The terminal determines one or a group of uplink transmission parameters from the different uplink transmission parameters as the uplink transmission parameter. One implementation method is: for a certain uplink transmission parameter or a certain category of uplink transmission parameters, the terminal determines the maximum value among the multiple transmission parameters associated with multiple uplink channel resources as the uplink transmission parameter. For example, with respect to the code rate, the terminal determines the maximum value among the multiple code rates associated with multiple uplink channel resources as the code rate.

[0125] In another embodiment, for a certain uplink transmission parameter or a certain type of uplink transmission parameter, the terminal determines the minimum value among multiple transmission parameters associated with multiple uplink channel resources as the uplink transmission parameter. For example, for a code rate, the terminal determines the minimum value among multiple code rates associated with multiple uplink channel resources as the code rate.

[0126] In another embodiment, for a specific uplink transmission parameter or a specific category of uplink transmission parameters, the terminal determines the transmission parameter associated with the first uplink channel resource among multiple uplink channel resources as the uplink transmission parameter. Optionally, the first uplink channel resource may be the first configured by the network, the first determined according to a protocol agreement, the channel resource with the smallest ID, the smallest associated time slot, or the smallest symbol. For example, for a code rate, the terminal determines the code rate associated with the uplink channel resource with the smallest ID among multiple uplink channel resources as the code rate.

[0127] Based on the above method, the terminal can map the CSI report to multiple uplink channel resources, thereby avoiding the situation where the uplink channel resources cannot carry the CSI report.

[0128] In an optional implementation, when a CSI report is associated with multiple uplink channel resources, the terminal determines the uplink channel resource, maps the CSI report to the determined uplink channel resource, and feeds it back to the network. Therefore, in this optional implementation, the terminal feeding back the at least one target CSI report based on the determined multiple uplink channel resources may include: the terminal determining at least one uplink channel resource from the multiple uplink channel resources, mapping all or part of the target CSI report to the determined at least one uplink channel resource, and feeding it back to the network-side device. In this implementation, the terminal may determine one uplink channel resource from multiple uplink channel resources, and then carry all or part of the CSI report to the determined uplink channel resource.

[0129] Optionally, the terminal determines at least one uplink channel resource from the multiple uplink channel resources, maps the target CSI report to the selected at least one uplink channel resource, and feeds it back to the network-side device in one embodiment: the terminal determines an uplink channel resource from the multiple uplink channel resources based on the payload size of the target CSI report, and then carries the entire content of the target CSI report on the determined uplink channel resource. That is, there is at least one uplink channel resource among the multiple uplink channel resources associated with the target CSI report that can carry the target CSI report. The determined one uplink channel resource can be the first configured uplink channel resource, or the earliest uplink channel resource, or the earliest PUCCH resource, or the first configured PUCCH resource among the at least one uplink channel resource that can carry the target CSI report. In particular, when all uplink channel resources cannot carry the target CSI report, the terminal carries the CSI report on the uplink channel resource that occupies the largest time-frequency resource or on the uplink channel resource that can carry the most CSI report content. Alternatively, when all uplink channel resources cannot carry the target CSI report, the terminal carries the CSI report on the earliest sent uplink channel resource that occupies the largest time-frequency resource or the earliest sent uplink channel resource that can carry the most CSI report content.

[0130] Optionally, the terminal determines at least one uplink channel resource from the multiple uplink channel resources, maps the target CSI report to the determined at least one uplink channel resource, and feeds back the target CSI report to the network device in one embodiment: the terminal determines a third uplink channel resource from the multiple uplink channel resources; and the terminal maps the first part of the target CSI report to the determined third uplink channel resource and feeds back the target CSI report to the network device. In this optional embodiment, the third uplink channel resource may be at least one uplink channel resource agreed upon in a protocol or at least one uplink channel resource indicated by network signaling. Further, optionally, the terminal may select an uplink channel resource from a portion of the multiple uplink channel resources associated with the target CSI report indicated by the network device based on the payload size of the first part of the target CSI report. If all uplink channel resources associated with the target CSI report cannot carry the first part of the target CSI report, the terminal selects the uplink channel resource with the greatest carrying capacity to carry the CSI report, and further discards the unloadable content of the CSI report in the order or manner agreed upon in the protocol. Alternatively, the terminal does not feed back the target CSI report. The content of the first part of the CSI report is content agreed upon by the protocol, and may include some channel state information, or may only include some indication information.

[0131] Optionally, the terminal determines at least one uplink channel resource from the multiple uplink channel resources, maps the target CSI report to the determined at least one uplink channel resource, and feeds back the target CSI report to the network side device in another embodiment: the terminal determines a third uplink channel resource from the multiple uplink channel resources, maps the first part of the target CSI report to the determined third uplink channel resource, and feeds back the target CSI report to the network side device; then, the terminal selects a fourth uplink channel resource from the multiple uplink channel resources according to the size of the second part of the target CSI report, wherein the second part is the part of the target CSI report other than the first part; the terminal maps the second part of the target CSI report to the selected fourth uplink channel resource and feeds back the target CSI report to the network side device.

[0132] Optionally, the third uplink channel resource includes one of the following:

[0133] The first configured uplink channel resource among the multiple uplink channel resources; optionally, the third uplink channel resource may be an uplink channel resource of a specific format that is first configured among the multiple uplink channel resources;

[0134] The earliest uplink channel resource among the multiple uplink channel resources; optionally, the third uplink channel resource may be the earliest uplink channel resource of a specific format among the multiple uplink channel resources;

[0135] The third uplink channel resource may include a physical uplink channel resource or a logical uplink channel resource among a plurality of uplink channel resources. The specific format is an uplink channel resource format agreed upon by a protocol or an uplink channel resource format indicated by a network-side device.

[0136] Optionally, the terminal indicates the fourth uplink channel resource selected by the terminal in the first part of the target CSI report, and other parts of the target CSI report except the first part are mapped to the fourth uplink channel resource selected by the terminal and fed back.

[0137] Optionally, the terminal selects at least one uplink channel resource from the multiple uplink channel resources, maps the target CSI report to the selected at least one uplink channel resource, and feeds it back to the network side device in another embodiment: the terminal can divide the CSI report into two CSI sub-reports based on network agreement, wherein the first CSI sub-report is mapped to an uplink channel resource indicated by the network or agreed upon by the protocol, and for the second CSI sub-report, the terminal selects an uplink channel resource from the multiple uplink channel resources, and then carries all or part of the content of the second CSI sub-report to the selected uplink channel resource. After the network side device obtains the first CSI sub-report, it can determine the uplink channel resource associated with the second CSI sub-report or the payload size of the second CSI sub-report or the content of the second CSI sub-report based on the content of the first CSI sub-report. If all uplink channel resources cannot carry the second CSI sub-report, the terminal selects the uplink channel resource with the largest carrying capacity to carry the second CSI sub-report, and further discards the content that cannot be carried in the second CSI sub-report in the order or manner agreed upon by the protocol.

[0138] Optionally, the terminal selects at least one uplink channel resource from the multiple uplink channel resources, maps the target CSI report to the selected at least one uplink channel resource, and feeds back to the network side device. Another implementation method may be: when the uplink channel resource agreed upon by the protocol or indicated by the network side device collides with other uplink channel resources, the terminal selects an uplink channel resource from the multiple uplink channel resources, and then carries the target CSI report to the selected uplink channel resource. Optionally, the terminal selects the first uplink channel resource that does not collide from the multiple uplink channel resources. The first one represents the first of the multiple uplink channel resources arranged in a certain order, for example, the first configured uplink channel resource, or the earliest uplink channel resource, or the earliest PUCCH resource, or the first configured PUCCH resource.

[0139] Through the above optional implementation, the content of the target CSI report can be fed back to the network device to the maximum extent possible, avoiding the problem of discarding the entire target CSI report or part of the target CSI report when an uplink channel resource cannot carry the target CSI report. Alternatively, this approach can also increase the flexibility of the network device in configuring uplink channel resources, avoiding the waste of resources caused by allocating too large uplink channel resources when the network device cannot determine the target CSI report size.

[0140] In an optional implementation, when a CSI report is associated with multiple uplink channel resources, the terminal maps the CSI report to at least one uplink channel resource based on the content of the CSI report and feeds it back to the network-side device. In this optional implementation, the terminal feeding back the target CSI report based on the determined multiple uplink channel resources may include: the terminal mapping the target CSI report to at least one uplink channel resource based on the content of the target CSI report and feeding it back to the network-side device.

[0141] Optionally, in the above optional implementation manner, when the terminal maps the target CSI report to multiple uplink channel resources, the CSI contents mapped to the multiple uplink channel resources have the same content.

[0142] In the above optional implementation, when the content of the target CSI report is specific content, the terminal maps the target CSI report to at least one uplink channel resource and feeds it back to the network-side device. For example, when the content of the target CSI report includes MTRP CSI, the terminal maps the target CSI report to at least one uplink channel resource and feeds it back to the network-side device. For another example, when the content of the target CSI report includes CSI of multiple different configurations, the terminal maps the target CSI report to at least one uplink channel resource and feeds it back to the network-side device.

[0143] Mapping, by the terminal, the target CSI report to at least one of the uplink channel resources and feeding it back to the network-side device according to the content of the target CSI report may include at least one of the following steps (not limited to a specific order):

[0144] Step 1: The terminal determines that the CSI report can be carried on at least one uplink channel resource;

[0145] Step 2: The terminal splits the CSI report into multiple CSI sub-reports, and determines the uplink channel resources on which the CSI reports need to be carried;

[0146] Step 3: The terminal carries or maps multiple CSI sub-reports to the uplink channel resources required to carry them and feeds them back to the network;

[0147] For step 1, the terminal may optionally determine, based on network signaling, that the target CSI report is carried on at least one uplink channel resource and fed back to the network-side device. Alternatively, the terminal may determine, based on protocol-agreed rules, that the target CSI report is carried on at least one uplink channel resource and fed back to the network-side device. For example, if the target CSI report is associated with multiple uplink channel resources, the terminal may determine that the target CSI report is carried on at least one uplink channel resource and feed back to the network-side device.

[0148] For step 2, optionally, if the terminal determines that the target CSI report is carried on at least one uplink channel resource and fed back to the network side device, the terminal can split the target CSI report into at least one CSI sub-report in accordance with the protocol agreement or network signaling instructions, and then determine at least one uplink channel resource associated with the at least one CSI sub-report in accordance with the protocol agreement or network signaling instructions.

[0149] A possible implementation method of the terminal splitting the target CSI report into at least one CSI sub-report in accordance with the protocol agreement or network signaling instructions is: if the target CSI report includes MTRP CSI, the terminal splits the target CSI report into multiple CSI sub-reports, wherein each CSI sub-report is associated with a TRP or a reference signal or a reference signal port group, or if the target CSI report includes multiple CSIs with different configurations, the terminal splits the target CSI report into multiple CSI sub-reports, wherein each CSI sub-report is associated with a CSI configuration or a CSI sub-configuration. Optionally, if there is part of the content in the target CSI report that is shared by multiple TRPs, for the feedback of these shared contents, an optional implementation method is: the network side device instructs the shared contents to be fed back to the network side device along with a certain CSI sub-report, that is, these shared contents are fed back only once. Another optional implementation method is: the protocol stipulates that these shared contents are fed back to the network side device along with a certain CSI sub-report, or the protocol stipulates that these shared contents are fed back to the network side device along with the first CSI sub-report, that is, these shared contents are fed back only once. Another optional implementation is: the terminal instructs the network device to feed back the shared content along with a CSI sub-report, i.e., the shared content is fed back only once, and the network device is instructed to do so. Another optional implementation is: the terminal feeds back the shared content in each CSI sub-report, i.e., the shared content is fed back at least once, as per protocol or instructions from the network device.

[0150] Optionally, the terminal may determine the uplink channel resources associated with each CSI sub-report according to protocol agreement or network signaling indication, for example, the network signaling indication or protocol agreement indicates that the first CSI sub-report of the terminal is associated with the first uplink channel resource, and the second CSI sub-report is associated with the second uplink channel resource. For another example, the terminal determines the uplink channel resources associated with each CSI sub-report based on the beam information associated with each CSI sub-report and the beam information associated with each uplink channel resource. For another example, the terminal determines the uplink channel resources associated with each CSI sub-report based on the TRP indication information associated with each CSI sub-report and the TRP indication information associated with each uplink channel resource. For another example, the terminal determines the reference signal associated with each uplink channel resource associated with the target CSI report through network signaling indication or protocol agreement. Further, when the terminal selects part of the reference signal to obtain MTRP CSI, the terminal feeds back the uplink channel resources associated with each CSI sub-report (each CSI sub-report is associated with one reference signal) carrying its associated reference signal to the network side device. Optionally, the protocol may stipulate that the reference signals and uplink channel resources correspond to each other in sequence according to the configuration order, that is, the number of uplink channel resources associated with the target CSI report is equal to the number of reference signals.

[0151] Optionally, when the terminal maps multiple CSI sub-reports to multiple uplink channel resources and feeds them back to the network side device, each CSI sub-report may also include an indication information, which is used to indicate the reference signal or reference signal port group or associated CSI sub-configuration or configuration associated with each CSI sub-report.

[0152] Through the above optional implementation, the network device can flexibly configure or instruct the terminal to divide the CSI report into multiple CSI sub-reports and feedback them on multiple uplink channel resources. This allows the network device to flexibly adjust the feedback of the target CSI report based on the actual backhaul link load or the channel quality of the air interface link, and to feedback the target CSI report to the network device or each TRP in a timely and complete manner as much as possible.

[0153] In an optional implementation, when a CSI report is associated with multiple uplink channel resources, the network side device may instruct the terminal through signaling to map the target CSI report to a certain uplink channel resource and feed it back to the network side device. In this optional implementation, the terminal may feed back the at least one target CSI report based on the determined multiple uplink channel resources, which may include: the terminal maps the target CSI report to the first uplink channel resource among the multiple uplink channel resources and feeds it back to the network side device in accordance with the instruction of the first network signaling, wherein the first uplink channel resource is at least one uplink channel resource indicated by the first network signaling. In this optional implementation, the uplink channel resource of the network side device through the first network signaling may be one of the multiple uplink channel resources preconfigured by the network side device.

[0154] For example, the network side device can update or change the uplink channel resources associated in the CSI report configuration signaling associated with a target CSI report through MAC CE, where multiple uplink channel resources are pre-configured in the CSI report configuration signaling. Optionally, the multiple uplink channel resources are associated with multiple BWPs, and each BWP is associated with multiple uplink channel resources.

[0155] For another example, the network side device activates a target CSI report and associates multiple uplink channel resources through DCI. Further, the network side device directly or indirectly indicates to the terminal through DCI which uplink channel resource the target CSI report is associated with.

[0156] In an optional implementation, when a target CSI report is associated with multiple uplink channel resources and the target CSI report includes multiple CSI report parts, the network side device can also indicate the uplink channel resource associated with each CSI report part through signaling. That is, the network instructs the terminal through signaling to map each CSI report part of the CSI report to which uplink channel resource and feeds it back to the network. Furthermore, the indicated uplink channel resource is one of the multiple uplink channel resources preconfigured by the network. In this optional implementation, the terminal feeding back the at least one target CSI report based on the determined multiple uplink channel resources may include: the terminal maps each part of the target CSI report to a second uplink channel resource among the multiple uplink channel resources and feeds it back to the network side device in accordance with the instructions of the second network signaling, wherein the second network signaling is used to indicate at least one of the second uplink channel resources associated with each part of the target CSI report. In this implementation, the second network signaling is used to indicate at least one second uplink channel resource associated with each part of the target CSI report, and the terminal maps each part of the target CSI report to at least one second uplink channel resource associated with the part and feeds it back to the network side device.

[0157] For example, the network device activates a target CSI report and associates it with multiple uplink channel resources via DCI. Furthermore, the network device directly or indirectly indicates to the terminal via DCI which uplink channel resource(s) the target CSI report part 1 is associated with, and which uplink channel resource(s) the CSI report part 2 is associated with. Optionally, when the network device does not indicate otherwise, the terminal may assume that parts 1 and 2 of the target CSI report are associated with the same uplink channel resource.

[0158] For another example, the network-side device may update or modify the uplink channel resources associated with CSI report part 1 and the uplink channel resources associated with CSI report part 2 of a target CSI report through a MAC CE. The CSI report configuration signaling pre-configures multiple uplink channel resources. Optionally, the multiple uplink channel resources are associated with multiple BWPs, and each BWP is associated with multiple uplink channel resources.

[0159] Through the above implementation, the network device can flexibly configure or instruct the terminal to associate the target CSI report or part of the target CSI report with the uplink channel resources. This allows the network device to flexibly adjust the feedback of the target CSI report based on the actual channel quality of the air interface link, and to provide the network device with the most complete target CSI report possible.

[0160] In an embodiment of the present application, in order to improve the processing speed and capability of the terminal, the mapping of a CSI report to multiple uplink channel resources and the feedback to the network-side device may be further limited. Therefore, in an optional implementation, the terminal feeds back the target CSI report based on the determined multiple uplink channel resources, including one of the following:

[0161] (1) When the target CSI report includes at least two CSI report parts, the terminal maps the target CSI report to multiple uplink channel resources and feeds it back to the network side device; in this optional implementation, only when the target CSI report includes at least two CSI report parts, the terminal maps one CSI report to multiple uplink channel resources and feeds it back to the network side device.

[0162] Optionally, the network-side device configures a target CSI report to be associated with multiple uplink channel resources. When the target CSI report is associated only with CSI report part 1 (Part 1) or includes at least two CSI report parts, the terminal maps the target CSI report to the multiple uplink channel resources and feeds them back to the network-side device. The multiple uplink channel resources can be a plurality agreed upon by the protocol or a plurality selected by the terminal.

[0163] (2) when the target CSI report includes a CSI report part, the terminal maps the target CSI report to one of the uplink channel resources and feeds it back to the network side device, wherein the network side device configures multiple uplink channel resources for the target CSI report;

[0164] Optionally, the network-side device configures a target CSI report to be associated with multiple uplink channel resources. When the target CSI report is associated only with CSI report part 1 (Part 1) or the target CSI report includes only one CSI report part, the terminal maps the target CSI report to one uplink channel resource and feeds it back to the network-side device. The one uplink channel resource can be one agreed upon by the protocol or one selected by the terminal.

[0165] (3) In the case where the target CSI report is associated with multiple target objects, the terminal maps the target CSI report to multiple uplink channel resources and feeds them back to the network side device, wherein the target object includes one of the following: carrier, cell, transmission and receiving node (TRP), reference signal, bandwidth part (BWP), subband set, resource block (RB) set, symbol set, and time slot set.

[0166] This implementation can be understood as follows: the protocol stipulates that only when the target CSI report is associated with at least one of multiple carriers, multiple cells, multiple TRPs, multiple reference signals, multiple bandwidth parts (BWPs), multiple subband sets, multiple resource block (RB) sets, multiple symbol sets, and multiple time slot sets, the terminal maps one target CSI report to multiple uplink channel resources based on network configuration or protocol agreement and feeds it back to the network side device. Alternatively, this implementation can be understood as follows: if the network side device configures one target CSI report to be associated with multiple uplink channel resources, when the target CSI report is only associated with one carrier, one cell, one TRP, one reference signal, one bandwidth part (BWP), one subband set, one resource block (RB) set, one symbol set, or one time slot set, the terminal maps the target CSI report to one uplink channel resource and feeds it back to the network side device. The one uplink channel resource can be one agreed upon by the protocol or one selected by the terminal.

[0167] The above optional implementation method can help the terminal determine in advance whether it is necessary to map a CSI report to multiple uplink channel resources and feed it back to the network, which helps to improve the processing speed and capability of the terminal.

[0168] In an optional implementation, for the case where multiple target CSI reports are associated with multiple uplink channel resources, the terminal may feed back the multiple target CSI reports based on the determined multiple uplink channel resources, which may include: the terminal maps the multiple CSI reports to at least one uplink channel resource according to the size of the multiple CSI reports and feeds them back to the network side device.

[0169] Optionally, the terminal mapping the multiple CSI reports to at least one uplink channel resource and feeding back the CSI reports to the network-side device according to their sizes may include at least one of the following steps (the order of execution of the steps is not limited):

[0170] Step 1: The terminal determines that the multiple target CSI reports cannot be carried on one uplink channel resource;

[0171] Step 2: The terminal determines that the multiple target CSI reports can be carried on multiple uplink channel resources;

[0172] Step 3: The terminal determines the uplink channel resources on which the multiple target CSI reports need to be carried;

[0173] Step 4: The terminal carries or maps multiple target CSI reports to the uplink channel resources that need to be carried and feeds them back to the network side device;

[0174] Step 5: The terminal splits the multiple target CSI reports into multiple CSI sub-reports;

[0175] Step 6: The terminal carries or maps the multiple CSI sub-reports to the uplink channel resources that need to be carried and feeds them back to the network device;

[0176] Step 7: The terminal determines the priorities of the multiple target CSI reports.

[0177] For the above-mentioned step 1, the terminal usually obtains the total payload size of multiple target CSI reports, and then the terminal determines a carried uplink channel resource, and the terminal determines whether the payload size that can be carried by the one carried uplink channel resource can carry the multiple CSI reports. Optionally, if multiple target CSI reports are associated with multiple uplink channel resources, the one carried uplink channel resource can usually be the first uplink channel resource indicated by the network-side device among the associated multiple uplink channel resources, or the earliest uplink channel resource among the multiple uplink channel resources, or an uplink channel resource of a specific format among the multiple uplink channel resources, or an uplink channel resource indicated by network signaling.

[0178] Optionally, if the bearer is possible, the multiple target CSI reports are carried on the uplink channel resources of a determined bearer and fed back to the network side device.

[0179] Optionally, if the target CSI reports cannot be carried, the terminal determines whether the multiple target CSI reports can be carried in multiple uplink channel resources (step 2). The determination method may be one of the following:

[0180] 1) The terminal determines, according to network signaling, that the multiple CSI reports can be carried on multiple uplink channel resources;

[0181] 2) The terminal determines according to the protocol that the multiple CSI reports can be carried on multiple uplink channel resources. For example, if the terminal determines that the target CSI report is associated with multiple uplink channel resources, the target CSI report can be carried on multiple uplink channel resources.

[0182] If the terminal determines that multiple target CSI reports cannot be carried in multiple uplink channel resources, optionally, the terminal does not feed back some CSI reports in the multiple target CSI reports according to the method agreed upon in the protocol, or carries part of the content in the multiple CSI reports on a determined uplink channel resource and feeds it back to the network.

[0183] If the terminal determines that the multiple target CSI reports can be carried in multiple uplink channel resources, optionally, the terminal determines the multiple uplink channel resources that the multiple target CSI reports need to be carried on (step 3). It can be understood that the terminal determines at least part of the uplink channel resources from the multiple uplink channel resources associated with the multiple target CSI reports to be used to carry the multiple target CSI reports. Optionally, the number of uplink channel resources determined by the terminal is agreed upon by the protocol or fed back by the terminal or indicated by network signaling. The corresponding determination method is similar to determining the uplink channel resources that the target CSI report is carried on from the multiple uplink channel resources associated with one target CSI report. For example, the terminal sorts the at least one uplink channel resource according to the time domain position and frequency domain position of each uplink channel resource, and determines the multiple uplink channel resources based on the sorting order. For another example, the terminal determines the multiple uplink channel resources that the multiple target CSI reports need to be carried on based on the target CSI report as the granularity and the payload size of each target CSI report. Optionally, after the multiple uplink channel resources are sorted in a certain order, the terminal determines the multiple uplink channel resources that the multiple target CSI reports need to be carried on. For another example, the terminal determines the multiple uplink channel resources that the multiple target CSI reports need to carry based on the CSI content in the target CSI report and the payload size of each CSI report. Optionally, after the multiple uplink channel resources are sorted in a certain order, the terminal determines the multiple uplink channel resources that the multiple target CSI reports need to carry.

[0184] Optionally, the terminal carries or maps multiple target CSI reports to the uplink channel resources required to carry them based on the target CSI report granularity and feeds them back to the network side device (step 4). It can be understood that no target CSI report is carried on two uplink channel resources.

[0185] Optionally, the terminal may split multiple CSI reports into CSI sub-reports with smaller granularity (step 5). For example, the terminal determines the first uplink channel resource for carrying the target CSI report and the payload size that can be carried, divides a part of the content from the multiple target CSI reports to form the first CSI sub-report, and then carries it in the first uplink channel resource. Further, the terminal determines the second uplink channel resource for carrying the multiple target CSI reports and the payload size that can be carried, divides a part of the content from the remaining multiple target CSI reports to form the second CSI sub-report, and then carries it in the second uplink channel resource, until all the contents of the multiple target CSI reports are carried in the multiple uplink channel resources. Optionally, when dividing the target CSI report, the terminal divides it according to the mapping order of the CSI report content agreed upon in the protocol. Optionally, when dividing the target CSI report, the terminal divides it according to the granularity agreed upon in the protocol, for example, the granularity is one row of the mapping table of the target CSI report agreed upon in the protocol.

[0186] For the above-mentioned step 3 or step 4 or step 6, optionally, there may be a situation where the terminal determines the priority of the multiple target CSI reports. For example, in the process of the terminal determining the multiple uplink channel resources that the multiple target CSI reports need to carry, the terminal sorts the multiple target CSI reports according to the priority of the multiple target CSI reports. Then, multiple uplink channel resources are selected based on the granularity of the CSI report. For another example, when the terminal maps multiple target CSI reports or CSI sub-reports to multiple uplink channel resources determined by the terminal, the terminal sorts the multiple target CSI reports according to the priority of the multiple target CSI reports, and then maps them to multiple uplink channel resources, or divides the sorted multiple target CSI reports into multiple CSI sub-reports, and then maps them to multiple uplink channel resources.

[0187] Optionally, the priority may be obtained through protocol agreement, or may be determined based on the configuration order of the reference signal, or may be determined based on network signaling, or may be determined based on the payload size of the target CSI report.

[0188] In an optional implementation, for multiple CSI reports associated with multiple uplink channel resources, the terminal may feed back the multiple target CSI reports based on the determined multiple uplink channel resources, including: the terminal determining the size of the multiple uplink channel resources, selecting an uplink channel resource from the multiple uplink channel resources, mapping the multiple target CSI reports to the selected uplink channel resource, and feeding back the feedback to the network side device.

[0189] Optionally, the terminal may determine, based on an instruction from a network-side device or a protocol agreement, that the terminal may select one uplink channel resource from a plurality of uplink channel resources for feeding back the plurality of target CSI reports.

[0190] Optionally, there may be a terminal that determines the priority of the multiple target CSI reports. Optionally, the priority may be obtained through a protocol agreement, or may be determined according to the configuration order of the reference signal, or may be determined according to network signaling, or may be determined according to the payload size of the target CSI report.

[0191] An implementation manner in which the terminal selects an uplink channel resource from multiple uplink channel resources associated with multiple target CSI reports may be: the terminal selects an uplink channel resource from multiple uplink channel resources to carry the multiple target CSI reports based on the total payload size of the multiple target CSI reports.

[0192] Another implementation method of a terminal selecting an uplink channel resource from a plurality of uplink channel resources associated with a plurality of target CSI reports may be: when an uplink channel resource agreed upon by the protocol or indicated by a network-side device collides with other uplink channel resources, the terminal selects an uplink channel resource from the plurality of uplink channel resources, and then carries the target CSI report to the selected uplink channel resource. Optionally, the terminal selects the first uplink channel resource that does not collide from the plurality of uplink channel resources. The first one represents the first one of a plurality of uplink channel resources that do not collide and are arranged in a certain order, wherein the arrangement order can be determined according to the priority order of the plurality of uplink channel resources.

[0193] In an optional implementation, for multiple CSI reports associated with multiple uplink channel resources, the terminal may feed back the multiple target CSI reports based on the determined multiple uplink channel resources, which may include: the terminal mapping the first part of each target CSI report to the same uplink channel resource and feeding it back to the network side device, and mapping the second part of each target CSI report to another uplink channel resource and feeding it back to the network side device, where the second part is the part of the target CSI report other than the first part.

[0194] In the above implementation, one implementation method in which the terminal maps the first part of each target CSI report to the same uplink channel resource and feeds it back to the network-side device is: the terminal maps the first part of each target CSI report to the same uplink channel resource, and the same uplink channel resource can be an uplink channel resource agreed upon by the protocol, for example, the first configured or activated uplink channel resource, or an uplink channel resource in a specific format agreed upon by the protocol, etc.

[0195] In the above implementation, the terminal maps the first part of each target CSI report to the same uplink channel resource and feeds it back to the network side device. Another implementation method is: the terminal maps the first part of each target CSI report to the same uplink channel resource, and the same uplink channel resource can be an uplink channel resource indicated by network signaling.

[0196] In the above implementation, the terminal maps the first part of each target CSI report to the same uplink channel resource and feeds it back to the network side device. Another implementation method is: the terminal maps the first part of each target CSI report to the same uplink channel resource, and the same uplink channel resource can be an uplink channel resource selected by the terminal.

[0197] Optionally, mapping the second part of each target CSI report to another uplink channel resource and feeding it back to the network side device can be understood as, for the remaining CSI content of multiple target CSI reports, the terminal selects an uplink channel resource according to the size of the payload, maps the remaining CSI content of the multiple target CSI reports to the selected uplink channel resource and feeds it back to the network side device, and the second part is the part of the target CSI report other than the first part.

[0198] Optionally, the uplink channel resources selected by the terminal for mapping the remaining CSI contents of the multiple target CSI reports may be uplink channel resources associated with the first part of the target CSI report, or may not be uplink channel resources associated with the first part of the CSI report.

[0199] Optionally, the time domain position associated with the uplink channel resources carrying the first part of each target CSI report is earlier than the uplink channel resources carrying the remaining CSI contents of the multiple target CSI reports.

[0200] Through the above optional implementation, multiple target CSI reports can be fed back to the network side device in a timely and effective manner, and there is no need to limit the network side device to allocate a continuous large uplink channel resource for multiple CSI reports, thereby improving the flexibility of resource allocation.

[0201] In an optional implementation, when there are multiple target CSI reports, the terminal feeding back the multiple target CSI reports based on the determined multiple uplink channel resources may further include: the terminal mapping the multiple target CSI reports to a fifth uplink channel resource among the multiple uplink channel resources and feeding it back to the network device in accordance with an instruction of a fourth network signaling, wherein the fifth uplink channel resource is the at least one uplink channel resource indicated by the fourth network signaling. In this implementation, the network device may indicate the at least one uplink channel resource to which the multiple target CSI reports are mapped through the fourth network signaling, and the terminal may map the multiple target CSI reports to the at least one uplink channel resource indicated by the network device. For example, the terminal may map the multiple target CSI reports to the at least one uplink channel resource in sequence according to priority, or the terminal may first map a first portion of the multiple target CSI reports to the at least one uplink channel resource, and then map a second portion of the multiple target CSI reports to the at least one uplink channel resource, where the second portion is the portion of the target CSI reports other than the first portion.

[0202] Through the above optional implementation, multiple target CSI reports can be fed back to the network side device in a timely and effective manner, and there is no need to limit the network side device to allocate a continuous large uplink channel resource for multiple CSI reports, thereby improving the flexibility of resource allocation.

[0203] Optionally, the association described in the embodiments of the present application is not limited to the following explanations:

[0204] A is associated with B, which means A is B;

[0205] A is associated with B, which means that B can be obtained through A;

[0206] A is associated with B, which means that B can be determined through A.

[0207] In an embodiment of the present application, the first network signaling, the second network signaling, the third network signaling, and the fourth network signaling may be the same network signaling or different network signaling. The network signaling may be high-layer signaling, low-layer signaling, MAC layer signaling, or physical layer signaling, which is not limited in the specific embodiment of the present application.

[0208] Based on the same technical concept, an embodiment of the present application also provides a method for obtaining a channel state information report.

[0209] Figure 5A flow chart illustrating a method for obtaining a channel state information report provided in an embodiment of the present application is provided. This method 500 can be executed by a network-side device. In other words, the method can be executed by software or hardware installed on the network-side device. Where necessary, the following embodiments only describe the operation of the network-side device. For other matters not covered, please refer to the above description of method 200.

[0210] like Figure 5 As shown, the method mainly includes the following steps.

[0211] S510: A network-side device sends a target network signaling to a terminal, where the target network signaling is used to determine a plurality of uplink channel resources associated with at least one target CSI report.

[0212] In an embodiment of the present application, when there are multiple target CSI reports, at least one target CSI report among the multiple target CSI reports is associated with multiple uplink channel resources, or at least one uplink channel resource among the multiple uplink channel resources is associated with multiple target CSI reports.

[0213] In an embodiment of the present application, the network-side device may optionally configure multiple uplink channel resources for target CSI report feedback for the terminal through target network signaling. Alternatively, the network-side device may also activate the configured target CSI report through target network signaling, thereby activating multiple uplink channel resources associated with the activated target CSI report.

[0214] Optionally, the target network signaling includes one of the following:

[0215] 1) high-layer signaling, where the high-layer signaling is used to configure the at least one target CSI report to be associated with multiple uplink channel resources;

[0216] 2) Multiple first DCIs; the multiple first DCIs are used to trigger the same target CSI report, for example, the multiple first DCIs trigger target CSI reports with the same CSI report ID.

[0217] 3) Second DCI: The second DCI is used to trigger multiple uplink channel resources and the at least one target CSI report. For example, the network-side device configures the target CSI report to be associated with multiple uplink channel resources through high-layer signaling, and then triggers the target CSI report and the multiple uplink channel resources through the second DCI.

[0218] S512: The network-side device receives the at least one target CSI report fed back by the terminal based on the multiple uplink channel resources.

[0219] In S510, the network side device may determine at least one uplink channel resource carrying the at least one target CSI report in accordance with the protocol agreement, or the network side device may determine multiple uplink channel resources carrying the at least one target CSI report based on the indication of the terminal, or the network side device may determine multiple uplink channel resources carrying the at least one target CSI report and instruct the terminal to receive the at least one target CSI report fed back by the terminal on the determined uplink channel resource.

[0220] In an embodiment of the present application, one target CSI report is associated with multiple uplink channel resources or multiple target CSI reports are associated with multiple uplink channel resources, so that when the network side device allocates uplink channel resources for feedback CSI reports, it is not necessary to search for a larger continuous uplink channel resource in order to avoid losing CSI report content, thereby improving resource allocation flexibility.

[0221] In an embodiment of the present application, the network-side device may receive the at least one target CSI report on at least one of the uplink channel resources in a manner corresponding to the feedback of the at least one target CSI report by the terminal.

[0222] In an optional implementation, when the number of the target CSI reports is one, the network-side device receives, based on the determined multiple uplink channel resources, the at least one target CSI report fed back by the terminal, including at least one of the following:

[0223] 1) The network-side device determines at least one uplink channel resource according to the size of the target CSI report, and receives the target CSI report fed back by the terminal on the at least one uplink channel resource;

[0224] In an optional implementation, the network side device may prioritize the multiple uplink channel resources according to the time domain position or frequency domain position of each uplink channel resource, determine at least one uplink channel resource that matches the size of the target CSI report in descending order of priority, and receive the target CSI report fed back by the terminal on at least one uplink channel resource.

[0225] For example, the network-side device receives the target CSI report fed back by the terminal on at least one uplink channel resource in descending order of priority of the multiple uplink channel resources.

[0226] 2) The network-side device determines a resource set of the multiple uplink channel resources, and receives the target CSI report fed back by the terminal on the resource set;

[0227] Optionally, the network-side device determines an uplink transmission parameter, and then receives the target CSI report fed back by the terminal on the resource union based on the uplink transmission parameter.

[0228] Optionally, the network-side device determines the uplink transmission parameter, including at least one of the following:

[0229] A) the network-side device determines, as the uplink transmission parameter, a maximum value among multiple transmission parameters associated with the multiple uplink channel resources;

[0231] C) the network-side device determines a transmission parameter associated with a first uplink channel resource among the multiple uplink channel resources as the uplink transmission parameter;

[0232] D) the network-side device determines the uplink transmission parameter based on a third network signaling sent to the terminal;

[0233] E) the network-side device determines the uplink transmission parameter based on a rule agreed upon in a protocol, wherein the rule agreed upon in the protocol is related to a transmission parameter associated with at least one uplink channel resource among the multiple uplink channel resources;

[0234] F) The network side device determines the uplink transmission parameter based on the default transmission parameter agreed upon in the protocol.

[0235] The network side device may determine the uplink transmission parameter in a manner corresponding to the terminal.

[0236] 2) The network-side device determines at least one uplink channel resource from the multiple uplink channel resources, and receives the target CSI report fed back by the terminal on the determined at least one uplink channel resource.

[0237] Optionally, the network-side device may select at least one uplink channel resource from the multiple uplink channel resources in the same manner as the terminal.

[0238] Optionally, the network side device determines at least one uplink channel resource from the multiple uplink channel resources, and indicates the at least one uplink channel resource to the terminal, and further receives the target CSI report fed back by the terminal on the determined at least one uplink channel resource.

[0239] Optionally, in one implementation, the network-side device may determine a third uplink channel resource from the multiple uplink channel resources, and receive the target CSI report from the third uplink channel resource.

[0240] Optionally, in another implementation, the network-side device may determine a third uplink channel resource from the multiple uplink channel resources, for example, by blindly decoding the multiple uplink channel resources to determine the third uplink channel resource, and receive the first part of the target CSI report fed back on the third uplink channel resource selected by the terminal.

[0241] Optionally, another implementation manner may be for the network side device to determine a third uplink channel resource from the multiple uplink channel resources. Receive the first part of the target CSI report fed back on the third uplink channel resource. Optionally, the third uplink channel resource may include one of the following: the first configured uplink channel resource among the multiple uplink channel resources; the earliest uplink channel resource among the multiple uplink channel resources; for example, the third uplink channel resource is the earliest physical uplink control channel resource among the multiple uplink channel resources, or the third uplink channel resource is the first configured physical uplink control channel resource among the multiple uplink channel resources.

[0242] Optionally, in another embodiment, the network-side device selects or determines a third uplink channel resource from the multiple uplink channel resources, for example, the network blindly decodes the multiple uplink channel resources to determine the third uplink channel resource. Receive the first part of the target CSI report fed back on the third uplink channel resource, and select a fourth uplink channel resource from the multiple uplink channel resources based on the size of the second part of the target CSI report, wherein the second part is the portion of the target CSI report other than the first part; the network-side device receives the second part of the target CSI report fed back by the terminal on the selected fourth uplink channel resource.

[0243] 3) The network-side device receives, based on the content of the target CSI report, the target CSI report fed back by the terminal on at least one of the uplink channel resources. For example, when the content of the target CSI report is specific content, the network-side device receives the target CSI report fed back by the terminal on at least one uplink channel resource.

[0244] 4) The network side device receives the target CSI report fed back by the terminal on a first uplink channel resource among the multiple uplink channel resources, wherein the first uplink channel resource is at least one uplink channel resource indicated by a first network signaling.

[0245] In this optional implementation, the network-side device may, through first network signaling, indicate that, when a target CSI report is associated with multiple uplink channel resources, it is to carry the uplink channel resources of the target CSI report and receive the target CSI report fed back by the terminal on the corresponding uplink channel resources. Optionally, the uplink channel resource indicated by the first network signaling is an uplink channel resource among the multiple uplink channel resources configured by the network-side device.

[0246] 5) The network side device receives the various parts of the target CSI report fed back by the terminal on at least one second uplink channel resource among the multiple uplink channel resources, wherein the second uplink channel resource is at least one of the second uplink channel resources associated with the various parts of the target CSI report indicated by the second network signaling. In this optional implementation method, the network side device can indicate through the first network signaling that when one target CSI report is associated with multiple uplink channel resources and the target CSI report includes multiple parts, the uplink channel resources carrying the various parts of the target CSI report are received on the corresponding uplink channel resources. Optionally, the uplink channel resources indicated by the second network signaling are uplink channel resources among the multiple uplink channel resources configured by the network side device.

[0247] In an optional implementation, when there are multiple target CSI reports, the network-side device receives, based on the determined multiple uplink channel resources, the multiple target CSI reports fed back by the terminal, including at least one of the following:

[0248] 1) The network-side device receives, according to sizes of the multiple target CSI reports, the multiple target CSI reports fed back by the terminal on at least one of the uplink channel resources;

[0249] 2) The network-side device determines sizes of the multiple uplink channel resources, selects or determines one uplink channel resource from the multiple uplink channel resources, and receives the multiple target CSI reports fed back by the terminal on the selected uplink channel resource;

[0250] 3) The network-side device receives the first part of each target CSI report fed back by the terminal on the same uplink channel resource, and the second part of each target CSI report fed back by the terminal on other uplink channel resources, where the same uplink channel resource is indicated to the terminal by the network-side device or determined based on a protocol agreement, and the second part is the portion of the target CSI report other than the first part. Optionally, the other uplink channel resources are determined by the network-side device based on channel resource indication information carried on the same uplink channel resource;

[0251] 4) The network side device receives multiple target CSI reports fed back by the terminal on at least one fifth uplink channel resource among the multiple uplink channel resources, wherein the fifth uplink channel resource is at least one uplink channel resource indicated by the third network signaling sent by the network side device to the terminal.

[0252] When receiving the target CSI report, the network-side device can use the same method as the terminal to determine the uplink channel resources mapped to the target CSI report and the content of the target CSI report carried on each uplink channel resource. For details, please refer to the relevant description in the above method 200, which will not be repeated here.

[0253] The technical solution provided by the embodiments of the present application can ensure that the terminal can provide timely and effective feedback of CSI reports, avoid waste of resources, and improve the flexibility of resource allocation.

[0254] The channel state information report feedback method provided in the embodiment of the present application can be executed by a channel state information report feedback device. In the embodiment of the present application, the channel state information report feedback method performed by the channel state information report feedback device is used as an example to illustrate the channel state information report feedback device provided in the embodiment of the present application.

[0255] Figure 6 A schematic diagram showing a structure of a feedback device for channel state information reporting provided in an embodiment of the present application is shown. Figure 6 As shown, the device 600 mainly includes: a determination module 601 and a feedback module 602.

[0256] In an embodiment of the present application, a determination module 601 is used to determine multiple uplink channel resources associated with at least one target CSI report, wherein, when there are multiple target CSI reports, at least one target CSI report among the multiple target CSI reports is associated with multiple uplink channel resources; a feedback module 602 is used to feed back the at least one target CSI report based on the determined multiple uplink channel resources.
